Laurie Metcalf plays Frasier's first wife, now a popular children's entertainer named Nanny G who reawakens lustful feelings in Frasier that are ardently reciprocated. There's just one slight hang-up: Nanny G has a new husband.

Guilty feelings seize Frasier, who, just for a thrill, swipes a medallion from his neighbor, a chatty, trusting widow. Now he sets out to secretly return the object, with the reluctant help of Niles.
